a Switching the chiral SPP modes. The as-deposited amorphous (AM) GST core is electrically heated beyond TC = 433 K, allowing it to transform into crystalline (CR) GST under Vg = 17 V. Vg = 25 V is applied to heat the CR-GST beyond TM = 873 K. Subsequent quenching leads to the melt-quenched (MQ) state GST. b Switching of the non-chiral SPP modes, where the AM-GST rod is electrically heated above TC = 433 K by using Vg = 10 V
